\ The Schedule referred to in these Letters Patent and making p art bfthe same.-

y Be it known that we, CHARLES Gr.V SAGENT, of vWestford, and ALFRED B.ELY', of'Newtoinin the State of Massachusetts, have made certainImprovements in Ootton-Gins, of which the following, with the" drawing,isa description.

Afpatent has been heretofore granted to A. B. ELY for an elastic roll,inv combination with dat plates,

whether one-or more,and whether'witb plain o1" ser rated edges, whenarranged andoperating"substantially as described.

Our improvementconsistslin using a recipfocating dat plate,with`serra`ted edges, in combination withan elastic or partially-elasticroll.

,A-.represents the frame. i Y i B, the roll,'having an elastic orsemi-'elastic surface. O, theat plate,"with serrated edge,`reciprocating in close proximityto the snrface of the roll. Disthecrank, for revolvingtherroll. E is a grcoved cam-pulley, at the otherend Vof' 'the axis of the roll, into the groove of4 which projects'apoint fromthe plate, by nea's f lwhich the plate is reciprqcated F aregrate-bars.

Any further description is needless to those ac` dnaintedwithcotton-gins. Y

'lfhe cotton `and seeds being fed up to the roll, the

fibre isdrawn ofi' by the action of the roll,` while the seeds areknocked off vagainst the edge of the plate.

This edge being serrated, and reciprocating, assists in the manipulatoryprocess. Y

The serrated, or corrugated edge f the plate is placedso that the fibreis' brought down,l in the direction of the arrow, toward and under theplate, from the edge downward, while the seeds, 85o., are retardedand'knocked ,o by and against the edge; and this arrangement,combination, and mode of operation is, we

believe,ne'w, bymeans of thev reciprocation of the plate-edge toward the'coming fibre, which is fed in v upon the top of the roll and grates.

'What we claim, is

An elastic or partially elastic-surfaced roll,.in comvbination witha'recprocating guard-plate, having aY serrated, or corrugated edge,arranged. and operating substantially as described. In testimonywhereof, we have hereunto subscribed our names. OHAS. G. SARGENT.
